Yesterday I downloaded Ubuntu 12.10 and I installed it along side my Windows XP installation. Then since it was running slow, I decided to remove XP. I decided to do a fresh install of Ubuntu via USB.
So when I was installing it, it detected that my PC has a Windows XP installation, but it didn't show that I already have Ubuntu or anything like that. Should I continue just by formatting Windows XP or should I do something else?
